5 Claims. (01. so -1 72) My invention relates to a putty remover, and Ideclare the following to be a full, clear, con-. oiseand exact description thereof suflicient to enable anyone skilled in the art to which it appertains to make and use. the same, reference being. had to the accompanying drawings in which like characters refer to like parts throughout.;

The objectof the invention is to provide a device that will remove putty from the wooden frame bars between the panes of glass usedin roofing greenhouses. To this latterendthe device is constructed to straddle the .bar that separates the panes in the window, whereby to remove the putty from both sides simultaneously.

The. device will be found useful also in removing the putty from the frame bars between the panes and from the edges of the window sash.

The object will be understood by referring to the drawings in which Fig. 1 shows a perspective view of the device.

Fig. 2 shows a perspective view looking at the side opposite to that shown in Fig. 1.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 4.

Fig. 4 is a plan view looking up from beneath.

Big. 5 is a detail view showing certain parts of F'the device.

Fig. 6 is adetail' view showing a perspective of one of the knives embodied'in the device.

Fig. '7 is a detail view showing a perspective of a' member for holding a knife in position. 5 Referring more particularly to-the drawings, the iputty remover embodies a pair of runners I, I which are held in parallel spaced relation by a plate 2 having laterally extending sides 3, 3 and an upstanding channel member 4. The upper surfaces of runners l, I are formed with counter-sunk recesses for holding the upper surface of flanges 3, 3 flush with the upper surface of runners I, I. Plate 2 is provided with recesses 5, 5 made in laterally projecting members 3, 3 for the reception of screw bolts 6, 6 which are threaded into bores in runners I, I. Each of the bolts 6, 6 is provided with a head I having ner Each of the members 20, 20 is held in position by a bolt 22 having a socket head 23 for the application of a socket wrench. Furthermore, each of the members 20 has an offset part;24 that engages a groove 25 formed in each of the knives I5, whereby to hold said knives {5, I5 in position. I

The rear end of each of the runners I, I has lateral recesses for the partial reception of rollers having reduced ends that provide shafts having bearings in the contiguous parts of runners I, I. The outer peripheral surfaces of rollers 33, 3t areinline with the outer edges 32, 32 of knives I5, I5, whereby .to hold said knives l5, I5 in maximum cutting position. Said rollers 30 also aid in reducing friction.

The means for limiting .the lower most position to which the knives I5, I5 can descend on either side of the barof the window sash embodies. a roller 35 mounted to turn on a shaft 36 carried in hearings in the bifurcated end 31 of lever arm38. 1 i

Lever arm 38 is pivoted to turn on a shaft 40 carried in bearings-in opposite sides of the channel member 4 of plate 2. The means for limiting the upward swing of lever arm 38 embodies a headed screw bolt 4| having a threaded aperture in the top part ofchannel member 4. It also projects downthrough plate 42 of the handle 43, hereinafter mentioned. A look nut 45 is mounted on said bolt 4| to hold said bolt 4i in adjusted position. Lock nut 45 has vertical recesses for the application of a spanner wrench, not shown.

Handle 43 comprises gripping part and plate 42 bent to form substantially a V. The upper end of plate 42 is held to the beveled fiat surface 5| of grip 50 by a headed screw bolt 52. The lower part of plate 42 is held to the lower flat surface of grip 50 by screw bolt 53 that engages a threaded recess in the upper surface of channel member 4. It is held also by screw 54 projecting upward through plate 42 into grip 50. A screw bolt 55 projects through plate 42 and engages a threaded aperture in the upper surface of channel member 4 of plate 2, whereby to hold said handle 43 thereto.

The means for allowing one of the runners I to yield laterally with respect 'to the other, whereby to anticipate variation in the thickness of the putty to be removed from the sides of the bar of the window pane contemplates the lateral sliding motion of one of the runners I on one of the flanges 3 of plate 2. To this end a bar is bolted at BI, BI to runner I across the flange 3, whereby to hold said flange in the counter-sunk recess formed in the top surface of runner l. Bolts 63, 63 are rigidly mounted in one of the runners I and project laterally therefrom and through an angle plate 64 having loose apertures therefor. Headed nuts 65, 65 with knurled surfaces are threaded to the outer free ends of bolts 63, 63. Said nuts 65, 65 are held in predetermined position by. lock nuts 515 having vertical grooves for the application or; a spanner wrench. Furthermore, plate is held to flange 3 by screws 61 engaging threaded bores in said flange 3. Coil springs 68 are mounted on bolts 63.

l and the other end rests against'th'e; inner surface of plate 64, whereby to yieldingly hold. said runners I in given relation to the other runner I.

The operation of the device is efiecte'd by adjusting the roller 35 with relation to the lower surface of knives I5, 15 by turning bolt t}, whereby to limitthe upward swing ofdlever 38. This adjustment -of roller 35 will limit the depth to which knives I 5, {'5 can descend to cut the putty and yet not exert an abnormal pressure on the. window pane. Knives l5, 'i5 are mounted in the front ends of runners I, I with the half circular member 25 "engaging the grooves 2 5- in said knives 15, I5 andthen tightening screws 22, 22.

The device can then be placed with the runners One end of said springs BI rests. in a counter-sunk recess in the side of spanning the bars of the'window frame and the device moved therealong, whereby the knives M will. cut the putty on either side of said bar, and yet not break the window pane. In the'even't an obstruction orabnormally wide portion is reached one of the runners. 1 will yield laterally under pressure of springs 68.

In the event that user. wishes to cutithe putty along the inner edge of the windowsashhe may use one ofthe knives l5. and.v slightly turning the device at an angle.

Having thus described my invention, what I claim as new and desire to. secure by Letters Patent is as follows:

1. In a'putty remover, runners held in spaced parallel relation toea'ch other, whereby to span the bar of 'a' window framefknivesdetachably mounted to said-"runners for removing the petty from'the sides of said bar, members attached to said runners for holding saidk nives thereto and one of saidrunners mountedto move relative to the other, whereb vto allow-for a given amount ofyield' 2. In a :putty remover, a pair ofr-unners held me of this patent;

in spaced relation to each other, a plate member for holding said runners in adjustable position relative to each other, knives removably mounted to said runners for scraping putty from a Window bar, and a lever having a roller mounted thereto attached to said plate for holding the knives in given relation to the window bar.

3. In a putty remover, a pair of runners. a nlatemember deta r. monntedto a runners tor allowing one of said runners to. be held adjus'tably to said plate member, knives removably mounted to said runners, a lever having a roller mounted therein attached to said plate member, whereby to hold said knives in pre-determined relation to a window pane, and a handle attached to said plate member for moving said putty rem ves.

4. n a -putty remover, a pair of runners, a plate member detachably mounted to said runners, flanges formed on said plate, an angle member mounted. to one or .said.flanges, bolts mounted to said runnersand projecting through said angle plate, springsmonntedon said bolts between said runners. and said angle plate .forallowing one of said runners. to. be. held in .pr-eedetermined relation to. said plate. member, knives vremovably mounted to said runners, a lever having a roller mounted therein attached to said plate member, whereby to. :hold said. knives. in preedetermined relation towindow pane, and half circular mem-. bers mounted in said runnersto hold said knives in given relation to. the putty.
